[0002] Frameless doors are now widely used in new energy vehicles and have a certain sense of high technology. However, frameless doors are different from traditional framed doors in that the glass and the B-pillar trim are directly matched (framed doors are door frame sheet metal matched with the B-pillar, and the glass moves inside the door frame sheet metal). Therefore, the position of the glass relative to the surrounding parts not only affects the matching size quality of the entire vehicle, but also affects the glass lifting and sealing functions, which is crucial.

[0003] The existing body-in-white quality inspection method is: after the four door glasses and the two decorative panels installed at the B-pillar position are assembled, the matching dimensions between the door glasses and the decorative panels are inspected to see if they are reasonable, and whether there are problems with the manufacturing dimensions of the body-in-white are indirectly determined. When the matching dimensions between the door glasses and the decorative panels do not meet the requirements, the door glasses and decorative panels need to be removed and the body-in-white needs to be adjusted. After the adjustment is completed, the door glasses and decorative panels need to be installed again, and the inspection is repeated. This results in complicated inspection steps for the body-in-white, which seriously affects work efficiency. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0045] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0046] The existing body-in-white quality inspection method is: after the four door glasses and the two decorative panels installed at the B-pillar position are assembled, the matching dimensions between the door glasses and the decorative panels are inspected to see if they are reasonable, and whether there are problems with the manufacturing dimensions of the body-in-white are indirectly determined. When the matching dimensions between the door glasses and the decorative panels do not meet the requirements, the door glasses and decorative panels need to be removed and the body-in-white needs to be adjusted. After the adjustment is completed, the door glasses and decorative panels need to be installed again, and the inspection is repeated. This results in complicated inspection steps for the body-in-white, which seriously affects work efficiency.

[0047] The present invention provides a detection module.

[0048] See also Figure 1 and Figure 3 In one embodiment of the present invention, the detection module 100 includes: a main body 1, two first detectors 2, two second detectors 3 and a control device, the main body 1 has a first side 11 and a second side 12 relative to each other, the first side 11 is used to be installed to the installation position of the decorative panel of the B-pillar 220 of the white body 200, and the second side 12 is formed with two detection surfaces 13 and a detection protrusion 14 located between the two detection surfaces 13; the two first detectors 2 are correspondingly arranged on the two detection surfaces 13 to detect the first distance in the horizontal direction between the vehicle door 210 and the corresponding detection surfaces 13; the two second detectors 3 are correspondingly arranged on both sides of the detection protrusion 14 in the longitudinal direction to detect the second distance in the longitudinal direction between one side end of the vehicle door 210 and the detection protrusion 14; and the control device is electrically connected to the two first detectors 2 and the two second detectors 3.

[0049] The technical solution of the present invention obtains the matching size between the door glass and the decorative panel by measuring the matching size between the detection module 100 and the door 210, thereby determining whether the manufacturing size of the body-in-white is qualified. Specifically, since the door glass is determined by the position of the door 210, the position of the door glass can be obtained by obtaining the position of the door 210. In addition, the detection module 100 is set at the installation position of the decorative panel of the B-pillar 220 of the body-in-white 200, wherein the detection surface 13 and the detection protrusion 14 correspond to the part of the decorative panel that matches the door glass, and ensure that the positions after installation are the same. If the matching size between the door 210 and the detection module 100 meets the requirements, it means that the matching size between the door glass and the decorative panel meets the requirements, and further, it can be obtained that the manufacturing size of the body-in-white 200 is qualified. The size of the body-in-white 200 is detected by using the detection module 100. From the detection steps, the steps of installing the door glass and the decorative panel are omitted, and the detection is more convenient. From the perspective of the manufacturing process, the detection module 100 can be detected before the body-in-white 200 is assembled. When it is judged to be unqualified, it can be adjusted online. In the prior art, it is necessary to wait until the door glass and the decorative panel are assembled before the measurement can be performed. When the body-in-white 200 is measured to be unqualified, the door glass and the decorative panel need to be disassembled, and the body-in-white 200 needs to be adjusted again. After adjustment, the detection steps are repeated until the size of the body-in-white 200 is qualified. The process and steps of detecting and adjusting the size of the body-in-white 200 are complicated. This further highlights the superiority of using the detection module 100 to perform online detection on the body-in-white 200. The detection module 100 mainly measures two dimensions: the first distance between the detection door 210 and the corresponding detection surface 13 in the horizontal direction, and the second distance between one side end of the door 210 and the detection protrusion 14 in the vertical direction. The first distance and the second distance are detected by the first detector 2 and the second detector 3, respectively. Among them, one detection module 100 can detect the front door 210 and the rear door 210 on one side of the body-in-white 200 at the same time, and the two detection modules 100 are respectively installed on the B-pillars 220 on both sides of the body-in-white 200, so as to determine the position information of the door 210 of the entire body-in-white 200 and obtain the conclusion whether the body-in-white 200 is qualified.

[0050] When it is detected that the first distance and the second distance data corresponding to each door 210 do not meet the requirements, it is necessary to let the workers know that an unqualified body-in-white 200 has appeared, so the detection module 100 also includes an alarm device, and the control device is also electrically connected to the alarm device, so as to control the alarm device to alarm when the first distance and the second distance are unqualified; in order to let the workers know the abnormal data of the body-in-white 200 and the position corresponding to the abnormal data, it is convenient for the workers to quickly and targetedly complete the rectification of the body-in-white 200. Therefore, the detection module 100 also includes a display device, and the control device is also electrically connected to the display device to control the display device to display the first distance and the second distance. Among them, the alarm device includes a sound alarm device or an optical alarm device.

[0051] See also Figure 2 In order to quickly and conveniently fix the detection module 100 on the B-pillar 220, in one embodiment, the first side 11 of the main body 1 is provided with a magnetic attraction portion 4, and the magnetic attraction portion 4 is used to be adsorbed and fixed on the B-pillar 220 of the body-in-white 200; it is convenient for installation and disassembly. When the detection module 100 is installed on the B-pillar 220, it is also necessary to position the detection module 100 to obtain the determined position of the detection surface 13 and the detection bump, so as to replace the decorative panel for measurement and detection. Therefore, the first side 11 of the main body 1 is provided with a positioning column 5, and the positioning column 5 is used to position with the mounting hole on the B-pillar 220 of the body-in-white 200. The positioning column 5 can be set as a polygonal column, or the number of the positioning column 5 is set to be multiple, so as to prevent the detection module 100 from rotating along the positioning column 5. Thus, a determined installation position is obtained.

[0052] For the distance detection device: the first detector 2 and the second detector 3, the first detector 2 and the second detector 3 can be set as laser distance measuring sensors and ultrasonic distance measuring sensors, etc., and reasonable selection can be made according to the requirements of working environment, measurement accuracy, cost control, etc.

[0053] Taking the first detector 2 as an example, what is detected is the distance between the detection surface 13 and the vehicle door 210, so the transmitting and receiving units of the first detector 2 need to be arranged on the detection surface 13, and other structures of the first detector 2 need to have space for installation, so as to ensure that the transmitting and receiving units of the first detector 2 need to be arranged on the detection surface 13, please refer to Figure 1The second side 12 of the main body 1 is partially recessed to form a first mounting portion 15, and the first detector 2 is installed in the first mounting portion 15 in the horizontal direction, so that the transmitting and receiving units of the first detector 2 are equivalent to the detecting surface 13 in the horizontal direction; the second detector 3 is installed in the same manner, and the two side walls of the detecting protrusion 14 in the longitudinal direction are partially recessed to form a second mounting portion 16, and the second detector 3 is installed in the second mounting portion 16 in the longitudinal direction, so that the transmitting and receiving units of the second detector 3 are equivalent to the outer side surface of the detecting protrusion 14 in the longitudinal direction. Such an installation method ensures accurate measurement of the distance between the vehicle door 210 and the corresponding measuring surface.

[0054] The present invention further proposes a body-in-white size detection method, which is based on a detection module 100. The specific structure of the detection module 100 refers to the above embodiment. Since the body-in-white size detection method adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0055] In order to simplify the steps of measuring the body-in-white 200 and the steps of assembling the body-in-white 200. Figure 4 , Figure 4 The figure is a flow chart of a first embodiment of a method for detecting dimensions of a body-in-white according to the present invention.

[0056] The present invention further provides a body-in-white size detection method, the body-in-white size detection method comprising:

[0057] Step S1: providing a detection module 100;

[0060] Step S4: judging whether the BIW 200 is qualified according to the first distance and the second distance.

[0061] By using the detection module 100 and the decorative panel installation position set on the B-pillars 220 on both sides, each door 210 of the body-in-white 200 is inspected. This detection method does not involve the installation of door glass and decorative panels. After the body-in-white 200 is manufactured, it can be inspected online. When the detection is unqualified, it can be adjusted immediately at this station to ensure that the body-in-white 200 produced by the body-in-white 200 production station is qualified, avoiding the need to disassemble the door glass and decorative panels after assembly and then adjust the body-in-white 200.

[0062] The determination of the body-in-white 200 is not only based on the matching size of the door 210, nor is it based on the data measured by the detection module 100 on one side, which is incomplete. Figure 5 , Figure 5 The figure is a flow chart of a second embodiment of a method for detecting dimensions of a body-in-white according to the present invention.

[0063] In one embodiment, step S4 includes:

[0067] Step S44: When any of the first distance and the second distance of the four doors 210 is judged to be unqualified, the body-in-white 200 is judged to be unqualified.

[0068] The measurement objects are the four doors 210, and a total of eight dimensions are obtained by the measurement. When all eight dimensions are qualified, the body-in-white 200 is qualified, and if one of the eight dimensions is unqualified, the body-in-white 200 is unqualified.

[0069] In order to let the workers know the abnormal data of the body-in-white 200 and the corresponding position of the abnormal data, it is convenient for the workers to quickly and specifically complete the rectification of the body-in-white 200. Figure 6 , Figure 6 The figure is a flow chart of a third embodiment of a method for detecting dimensions of a body-in-white according to the present invention.

[0074] In one embodiment, after step S4, the method further includes:

[0075] Step S6: when the BIW 200 is determined to be qualified, the detection modules 100 installed on the B-pillars 220 on both sides of the BIW 200 are removed;

[0076] Step S7: Install the decorative panel and door glass.
